Researchers Map Genome of Thalassiosira pseudonana

NEW YORK, Oct. 1 (GenomeWeb News) - Researchers today announced the first genomic map of Thalassiosira pseudonana, an ocean-dwelling diatom. The research that yields this map was conducted by a team of more than 46 researchers from 26 institutions and appears in the Oct. 1 issue of Science.

"Now that we have a glimpse at the inner workings of diatoms, we're better positioned to understand how changes in the environment will translate into increases or decreases in diatom abundance," Dan Rokhsar, who heads computational genomics at the Joint Genome Institute and is one of the co-authors on the article, said in a statement.

The investigation, funded by the Department of Energy and conducted at its Joint Genome Institute in California, gives insight into how the diatom species Thalassiosira pseudonana functions in the marine environment, according to a statement.

The single-celled organisms generate as much as 40 percent of the 50 billion to 55 billion tons of organic carbon produced each year in the sea, and in the process use carbon dioxide and produce oxygen.
